The ideal height of sauna is seven feet as the low ceiling ensures adequate heat supply for upper bench occupants. Proper ventilation is essential to prevent stuffiness and discomfort. The doors left open can bring down the temperature of sauna defeating its very purpose. An insulated room of softwood and a good heater are a must for sauna.

The amount of heat varies with the height of the bench. When deciding up on the size of the sauna, consider the number of users. Each occupant may need two feet of bench space. Saunas can be installed in any part of the house as plumbing connections are not needed. A suitable electrical circuit is a must for the sauna heater. Heaters may need 120 volts to 240 volts of power. The foremost item to be identified when building a sauna is the heater. The heater could be wood, gas, or electric based on geography of the area where sauna is to be installed. Wood based heaters would be the best choice in an area with abundant firewood, because they give off a nice aroma. In urban environments, gas or electricity heaters would be a practical option. Building and environmental laws of the area would also play a decisive role in the selection process.

The ideal location of sauna would be near river, lake, sea or other water bodies as cooling is necessary after sauna. Or, placing the sauna in your home is always great.
